SELF-ALIGNING TAKE-UP BOX AND ROLLER BEARING.

Application filed July 30,

Mv resent invention. has

for its object to provide a simple and highly efiicient selfaligningtake-up box for ele the like and a roller bearing boxes, pillow blocks,rigid like, and to this end sists of the novel vator boots and fortake-up boxes and the generally stated, condevices and combinations ofdevices hereinafter described and defined in the claims.

In the accompanying drawings, which i llustrate the invention, likecharacters indicate like parts throughout the several views.

.and head block 12 constitute a frame or a box, pear.

Mounted between the pairs of rails 10 is an open faced housing 15 havinga spherical periphery which engages the rails 10 and guides the housing15 for raising and lowering movements and at the same time permitsuniversal movements thereof. The housing 15 is held suspended betweenthe rails 10 by a long take-up screw 16, the lower end of which isreinovably swivelled at 17 in the top of the housing 15 and held by akey 18 against removal therefrom. The key 18 is held against removalfrom its seat by the web of one of the channel bars 9.

The take-up screw 16 extends loosely through a pair of aligned holes inthe flanges of the head block 12 and has applied there to a nut 19mounted in the channel of said head block which holds the same fromturning, but with suflicient angular movement of the take-up screw 16during the universal movements of the housing 15. Said take-up screw 16has a square end 20 for the application of a wrench to turn said screwto raise or lower the housing 15.

lVithin the housing 151 is a roller bearing of well known commercialmake which comprises rollers 21 and inner and outer races 22 and 23,respectively. By reference to Fig. 2 it will be noted that the innerends of the races 22 and 23 engage the back of the housing 15 and thatthe inner race 22 is considerably wider than the outer race 23 andprojects outward thereof. A ring 24 is telescoped over the outerprojecting end of the inner race 22 and its inner face engages the outerend of the outer race 23. The length of the rollers 21 is such that theyare free to turn between the back of the housing 15 and the ring 24.

Integrally formed with the ring 24 is an outturned peripheral flange 25,and a face plate 26 is rigidly but detachably secured by a screw 27 tothe housing 15. This face plate 26 is engaged by the flange 25 on thering 24 and clamps said ring and the outer race 23 together and betweensaid face plate and the back of the housing 15, the same from turning inrespect. to said housing. To further secure the outer race 23 fromturning in the housing 15, the same is secured thereto by a pin 28.

A shaft 29 is mounted in the inner race for a purpose that willpresently apclearance to permit and holds :permit free rotation of saidflange 31. common key 321s provided inner race 22 and the collar 30 tothe shaft housing is a nipple fingers 35 which extend the head blockscrews 16 -30 applied thereto which extends loosely through an axialaperture-in the faceplate 26. This collar 30 has an external flange 31integrally formed with its inner end, which loosely fits between thering 24 and face plate 26 and within the'flange to for securing the 29for rotation therewith, as shown in Fig. 2. A set screw 32 holds the key32 against endwise movement in respect to the shaft 29 and in turnholdsthe collar; 30 against axial Attached to the movement on said shaft.

Obviously, the collar 30 and its flange 31 hold the shaft29 against endthrusts in either direction. It is also evident that the housing 15 isself-aligning with the shaft 29 in the various different positions itmight take.

To prevent the housing 15 from turning with the-shaft 19 there isintegrally formed with said housing upper and lower pairs of between therails 10 of each pair and arranged to engage the webs of. thechannelbars '9. The width of the fingers'35 is such as not to interferewith the endwise movement of the housing 15 between the rails 10.

By removing either the crosstie bar 11 or 12, the housing 15 and theparts carried thereby may be lifted fromthe frame. After the housing 15hasbeen moved into a position in which the key 18' extends either aboveor below thechannel bars 9, said key may be removed to release-thetake-up from the housing 15.

In this I outer end portions of ing, aspacing faceplate, said spacing flange, ring and outer 36 is mounted ina structure, the housing pillow block 51.
